The same goes for no2trump.com, trumpmustgo.com and two dozen other web addresses that sound like they're bashing the billionaire Republican presidential nominee, his business interests or his political aspirations.

What would Trump want with such insulting domains? Easy. To make sure his critics and rivals can't have them.

He and his Trump Organization own more than 3,600 web addresses, according to the research firm DomainIQ. The vast majority bear the names of his properties, products and progeny. There are 274 domains alone featuring the name of Trump's daughter Ivanka.

And then there are the ones that seem better suited for the anti-Trump crowd: eight domains ending in "scheme," eight ending in "fraud" and eight ending in "sucks."

It is common for businesses and celebrities to scoop up and sit on web addresses that could be used to mock or attack them.

Colleges have made a habit of buying up versions of their names ending in .xxx to prevent them from falling into the hands of pornographers, and Major League Baseball has registered the names of various teams ending in .sex.

"Domains are cheap," branding expert Rebecca Lieb said. "Mopping up when somebody acquires a domain and does something malicious with it is expensive."

Trump's collection of web addresses good and bad is far more extensive than that of any candidate before. He and the Trump Organization own a few hundred more than Target Corp. or General Motors.

Hillary Clinton's campaign owns 70, according to DomainIQ, though none appear to be the kind of derogatory names Trump has registered. Her family's foundation owns 214 domains, including four ending in .xxx.
